Step 1

Preheat oven to 400°F. Cut each peach in half, and remove pit. Set aside.

Step 2

Stir together brown sugar, butter, and cinnamon in a small bowl to combine.

Step 3

Unroll 1 of the piecrusts, and use a rolling pin to slightly flatten. Cut dough into 1 1/2-inch strips. Lay 2 strips in an “x” shape. Place 1 peach half in center of “x” and top peach with 2 teaspoons of the brown sugar mixture in the pit hole. Cut the 2 bottom, and top left strips of dough in half lengthwise. Wrap dough strips over peach in a lattice pattern. Reserve excess dough to be rolled out and cut into strips. Place wrapped peach half on a rimmed baking sheet lined with parchment paper. Repeat process with remaining dough, peach halves, and brown sugar mixture.

Step 4

Lightly whisk together egg and water. Brush peach pies with egg wash, and bake in preheated oven until golden brown, about 20 minutes. Let stand 4 minutes. Serve warm.
